Research On New Techniques Of GPU-based SPH Fluid Deformation Control

Physics-based fluid deformation control has been a hot topic in the field of computer graphics.The SPH fluid deformation control for fluid deformation control and fluid tactile interaction for model deformation is an important part of fluid deformation control.This research has strong application value in the field of game animation,digital entertainment,and virtual simulation and so on.It remains a challenging problem to drive particles-based fluid simulation to match target shape and deforming fluid shape between different models smoothly in fluid control,especially when the natural fluid motion should be preserved.To achieve the desired behavior,we first divide models into source object and target object and generate control particles from them,respectively.Then,according to a space point correspondence method between source control particles and target control particles,we calculate the control particles' movement and drive fluid match different models directly.Finally,we transfer control energy from source control particles to target control particles so as to avoiding the leak of control energy and preserving fluid detail.The effectiveness of our method was demonstrated in various scenarios.In addition,in order to achieve real-time fluid control,this paper designs a GPU-based SPH solution process,greatly improving the efficiency of our work.Fluid control and virtual reality have become a research hotspot in recent years.In particular,the use of haptic interaction in virtual reality to control the deformation control of fluid model is still a challenging problem.In order to solve these problems,an SPH fluid deformation control method which based on the haptic interaction was proposed.Firstly,we sample the user specified object model by the voxelization method to get control model and control fluid's animation.Then,for realistic interaction effect,we calculate the deformation of the control model according to the user control force and the interaction force between the model and the fluid.Finally,a control method of deformation control of the fluid model is proposed.
